Popis: The hepatitis B core antigen (HBcAg) can generate a strong immune response and is recognized as an effective carrier for foreign epitopes. The domain-4 epitope of the anthrax protective antigen (PA-D4) plays an essential role in generating protective immunity against virulent Bacillus anthracis. Here we report the successful production of a recombinant protein comprised of the antigenic PA-D4 integrated into the c/e1 loop of HBcAg in transgenic low-alkaloid Nicotiana tabacum. Sera of mice injected with the plant-derived purified HB/PA-D4 protein exhibited significant anti-PA- and anti-HBcAg-specific IgG titers; however, formation of virus-like particles (VLP) was not observed. These data support the feasibility of producing complex protein chimeras in plants.
